Definitions

  • a multi-hop network comprises a multiplicity of network nodes, each having at least one transmitting/receiving means and one processor unit.
  • data are usually transmitted from a first network node, the data source, via a number of other network nodes, which serve as relay stations, so-called intermediate nodes, to a second network node, the data sink.
  • the first node as well as the second node can basically be selected randomly, permitting in this manner, data exchange between network nodes in a multi-hop network without their transmission and reception ranges overlapping, i.e. they are unable to communicate data directly with each other.
  • Any network node can be a data source, data sink or even a relay station.
  • the single nodes have to be positioned in relation to each other in such a manner that at least one other network node is located in its transmitting/receiving range in such a way that an interlinked communication structure can be created.
  • the invented method for synchronization and communication is based on a multi-hop network having a central node and a multiplicity of nodes.
  • the size of the network i.e. the network can comprise as many nodes as desired.
  • the method serves to retain the synchronization in normal operation of the network.
  • Communication between the individual nodes in a multi-hop network is based on wireless data transmission in frames, which are subdivided into defined slots.
  • two-directional communication methods used in particular are radio methods employing the following data transmission protocols: time division multiple access (TDMA), frequency division multiple access (FDMA), code division multiple access (CDMA).
  • TDMA time division multiple access
  • FDMA frequency division multiple access
  • CDMA code division multiple access
  • Subdivision of the frames into the data areas, preferably into a synchronization area, a neighbor node area, and a data area may be useful depending on the application, for example to transmit normal communication data and data for optimizing the network structure simultaneously in one frame.
  • the frame structure i.e. the frame duration, the number of slots or subdivision of the frames into areas
  • the network can be adapted to special conditions during operation.
  • 100 repeater nodes are created in a ten-story building with ten apartments on each floor. It may be a few less or more if an apartment is only partly detected by a beacon from the lower layer. In this case, it is advantageous to provide an additional repeater node in that part of the apartment that then belongs to the next higher layer.
  • FIG. 9 shows schematically the distribution of sensor nodes in a four-story building.
  • the individual sensor nodes (white circles) are assigned to individual apartment clusters on the floors. In each cluster, one sensor node is selected as the repeater node. Between the repeater nodes is a communication structure (black arrow), which permits communication between the repeater nodes and the central node on the ground floor of the building.
  • the individual sensor nodes always select the repeater node in their respective apartment cluster for communication with the central node, for example as predecessor.
